SCR Principles And Circuits | Nuts & Volts Magazine
An SCR (Silicon Controlled Rectifier) so that the alarm turns on when the temperature falls below a pre-set level, Figure 16 shows a particularly effective yet simple variable speed-regulator circuit. This uses an SCR as the control element and feeds half-wave power to the motor
Voltage regulator - Wikipedia
OverviewElectronic voltage regulatorsElectromechanical regulatorsAutomatic voltage regulatorAC voltage stabilizersDC voltage stabilizersA voltage regulator is a system designed to automatically maintain a constant voltage level. A voltage regulator may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages. Electronic voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elemenSee more on enpedia · Text under CC-BY-SA license
SCR voltage regulator | Electronics Forum (Circuits
Won't using just one SCR block every half cycle? You can just use a diode for that (why use an SCR?), then a lowpass filter to smooth out the voltage between negative half cycles and follow that with a zener diode to clamp the voltage to get a DC regulator.
TRIAC-Controlled Pre-Regulator With - Electronic Design
This idea implements a pre-regulator using a novel analog optical-feedback loop combined with an LED and light-dependent resistor (LDR). When applied to a 24-V, 1-A variable dc power supply, the linear regulator dissipates less than 7 W. The dc power supply’s input stage is a standard TRIAC light dimmer fed by the 230-V, 50-Hz mains .
A Three-phase AC-Voltage Regulator System
PDF fileThree-phase AC-voltage regulatior systems using silicon controlled rectifier (SCR) have been broadly applied in industrial field paper introduces a novel design of three-phase AC-voltage regulation trigger circuitry with SCR and STM32 microcontroller, and presents its application in an energy-saving design of oil extractor control system.
